wages in "The One Where Underdog Gets Away" and hires a professional musician, Stephanie Schiffer (played by Chrissie Hynde of The Pretenders), to replace Phoebe in "The One with the Baby on the Bus". He is last mentioned in "The One Where Rachel Quits", where he asks Rachel to retake the waitress training through Gunther, and when Rachel quits midway through the training, he promptly hires a new and more experienced waitress. He presumably retires in season 4 and from this point onwards Gunther becomes the sole manager at Central Perk. The role of Terry was intended by the NBC producers to be much bigger. They saw him as an older character who would provide advice to the six friends but NBC were talked out of it by the show's creators. Fun Bobby "Fun Bobby" (Robert) (Vincent Ventresca): Monica's alcoholic boyfriend. In his first appearance in "The One with the Monkey", his "fun" is sapped at Monica's New Year's party after his grandfather died, but his depression does not stop Monica, annoyed that he's "bringing her party down" from putting a party horn in his mouth and forcing him to blow on it, to his bemusement. In "The One with Russ", the gang discovers that alcohol puts the "fun" into Fun Bobby. Monica tries to wean him off drinking but regrets it when he becomes extremely boring. Monica then begins drinking on their dates, so that she could sit through his mind-numbingly dull stories. Bobby then breaks up with Monica, stating that he is not strong enough for a co-dependent relationship. It is revealed in the episode "The One with Phoebe's Husband" that the underwear on the telephone pole was Monica's when she was having sex with Fun Bobby on the terrace. David David, "the Scientist Guy" (Hank Azaria): a physicist with whom Phoebe falls in love in "The One with the Monkey", when he receives an academic grant for a three-year research trip to Minsk (incorrectly—and consistently—described in the scripts as being in Russia, rather than Belarus). After a quarrel with his research partner Max (Wayne Pére), Phoebe urges him to take the trip, even though it breaks her heart. Seven years later, he returns to New York for a brief visit and shares an evening with Phoebe, at the end of which he wants to say he loves her, but chooses not to as it will make it
